I've seen it and tried it before. It's... Okay. Decent amount of features but nothing much to get excited about (at least for an artist perspective, and the free version I had). But I'd imagine it would be engaging for someone more adept in 3D modeling.
For customized 3D artist references (specifically for females), I would definitely recommend DesignDoll. I've been using it for a while.
I got it the other day and have been walking around in it as I try to make a wild Candon appear. It's not really that hard to use but there are just so many buttons! Or maybe I just think it's not hard because I'm familiar with blender, ArchiCAD, SolidWorks, and DOGA.
I'm considering using this tool to make some character art for others, though I would need to be working close with them to make it to their liking.
